I have realized that Satan OTK in the mirror is giga overrated, t8 vtuber + t9 double barrier golem Norman completely negates that play and allows you to oneshot with Kuon and only 1 demonic spirit next round , so going first no longer is giga favored, since you can protect yourself on t9 .

All 7 of these were mirror matchups, the vtuber is just too good
